I am currently a postdoctoral researcher at the University of Pennsylvania advised by Sudeep Bhatia and funded by the NSF SPRF. My work aims to clarify the mental processes constituting human higher cognition and the representations over which they operate. More specifically, I am interested in human processing of analogy, causality, metaphor, similarity, sameness and difference, as well as memory search, recall, and recognition.
